Solothurn Inheritance Tax — Complete Guide
What executors and families need to know about the Canton of Solothurn’s inheritance tax (Erbschaftssteuer): who is taxed, what’s taxed, common exemptions for close relatives, situs rules for nonresidents, filing mechanics & deadlines, planning considerations, and case law highlights.
Solothurn Inheritance & Probate Basics
Who is taxed (conceptual)
Solothurn levies an inheritance tax that generally falls on the beneficiary’s share rather than on the estate as a whole. Many cantons grant full exemption for spouses and descendants; transfers to other relatives and unrelated beneficiaries are typically taxable with progressive scales.
How Swiss probate works (high-level)
After death: inventory of assets & debts, succession certificate (Erbbescheinigung), potential community of heirs (Erbengemeinschaft), and coordination with the local tax authority. Real estate transfers require land register updates and (often) tax clearance.

Solothurn Situs vs. Non-Situs Property (for Nonresidents)
| Asset type | Solothurn treatment (nonresident) | Notes |
|---|---|---|
| Real property in Solothurn | Included in Solothurn base | Primary trigger for nonresident filings and payments. |
| Tangible movables kept in Solothurn | Included | Artwork, vehicles, valuables physically located in Solothurn. |
| Intangibles (bank deposits, shares) | Generally follow domicile | Typically not Solothurn-situs for nonresidents. |
| Business with fixed facility in Solothurn | Potentially included | Allocation may apply to assets functionally tied to Solothurn. |
Inter-cantonal and cross-border coordination is used to avoid double taxation; provide consistent documentation across jurisdictions.

Planning Ideas to Reduce Solothurn Inheritance Tax
- Beneficiary mix & exemptions. Align dispositive provisions with cantonal relationship-based preferences (e.g., spouse/descendant treatment vs. others).
- Real estate strategy. Consider restructuring, gifting, or selling Solothurn immovable property in light of transfer taxes and valuation timing.
- Valuation readiness. Independent appraisals for property/closely held assets; document deductions and debts allocable to Solothurn-situs assets.
- Cross-border credits. Coordinate with foreign estate/inheritance tax systems to secure relief and avoid timing mismatches.
- Liquidity planning. Ensure cash to settle cantonal assessments without forced sales; review life insurance ownership/beneficiaries.

FAQs
Does Solothurn have an inheritance or an estate tax?
An inheritance tax (borne by the beneficiary’s share), not a U.S.-style estate tax on the estate as a whole.
Are spouses and descendants taxed?
In many Swiss cantons, spouses and descendants benefit from wide exemptions or strong preferences. Solothurn’s exact brackets and exemptions are set by cantonal law; verify current rules on our Forms & Deadlines page.
When is the return due and can I extend?
The tax office typically sets a due date via notice. Extensions can be granted on request; interest/penalties may apply if payment is late.

Primarily on Solothurn-situs assets (especially real estate). Most intangibles follow the decedent’s domicile. See the Nonresident Guide.
